The present invention relates to a construction for the housing and supporting of underground pipes or conduits which are used primarily in the transmission of steam, hot water, and other liquids or gaseous materials, or under any similar circumstances for the protection of conduits, the present application being a division of my co-pend ing application Serial No. 549,236, filed April 3, 1922.

The object of the invention is to provide a construction inwhich there is provided a drained base, which base is formed of crushed rock, coarse gravel, or any similar material, the base serving as a support for tile in which the pipes before mentioned are housed.

One of the objects of the invention is to provide a construction in which the pipe within the tile is supported at frequent in; tervals by means of suitable supports which are in turn carried by the base. Other objects of the invention will appear as the description proceeds. v

Reference should be had to the accompanying drawings forming a part of this specification, inwhich Fig. 1 1s a side eleva tion with portions in section, of a portion of a base with drain tile therein supporting other tile within which are housed suitable pipes; Fig. 2 is an end elevationof the showing in Fig. 1; Fig. 3 is a front elevation of a pipe support; Fig. 4 is 'a sectional elevation on the line 4-4 of Fig. 3; Fig. 5 is an elevation ofthe su port shown in Fig. 3; Fig. 6 is a top plan view of the base ortion of the support which is shown in ig. 3; Fig. 7 isa perspective view showing a block on which a pipe support is mounted;

the

Fig. 8 is a sectional elevation showing a tile is supported in a manner in which supporting block.

Referring to the drawings, and more particularly to Fig. 1,.1 indicates a base made up of crushed rock, coarse gravel, or any similar substance, in which base there is permanently located a series of common tile which is indicated at 2. The tile mentioned is the common ordinary unglazed tile of commerce, which isperfectly well known.

These tile are spaced aplart from each other, T

thereby leaving a slig t spacing which is is indlcated at 3. This construction permits the seepage of drainagewater through thebase portion 1, and this water will collect in the series of drain pipes and be conducted away to a point of discharge.

t lMounted upon the base 1 are a series of 1 e are preferably of the usual bell .and spigot type, and are preferably glazed. The bell portion of each tile occupies a suitable de pression which is formed .111 the base, so that the tile may be supported in proper align- TENr O-FFlCE.-

which are indicated -at 4. These tile ment.

At fre uent intervals throughout the length of t a base there are inserted blocks,-

one of which is indicated at5. The number a of blocks used in agiven installation andthe spacing of the same is purely an arbitrary matter and while there is only one I such block indicated in the construction shown in Fig. 1, it will be understood from the description given that there are in actual use a plurality construction.

The block which is indicated at 5 is more clearly shown in Fig. 7, in which it will be seen that the block has a rounding top surface 5, and that the edges of this top surface terminated in what may be termed beads 5 and 5.

Extending transversely of the block 5 of such blocks in a given .there is a slot 5.

On the-lower surface of the block 5 there is a rounded groove 5' which extends longitudinally of the block.

In using the block 5 it is placed in the base 1 so that the rounding portion 5 will straddle a tile 2, or two adjacent tiles, as the case maybe. The material of which the base 1 is composedis compacted around the block 5, so that it in effect forms an integral portion of the base.

The block 5' serves'as a support and positioning member for a pipe supporting device. Each pipe supporting member comprises a saddle portion which consists of a web member 6 having transversely extending end members 7 and 8, the inner surfaces of the end members being slanting, as indicated at 7 and 8 in Fi 3. At the central portion of the web mem er there is an upstanding loop 9 which has an opening through it, 10.

There is a central member which is generally indicated 'at 11, these members being provided with 'abase portion having an opening which straddles the loop member 9, and-for the purpose of securing the member 11 to the' loop member a retaining member or wedge 12 may be inserted, as indicated side members being formed. with elongated depressions at their upper ends, as indicated I at 15 in Figs. 4 and5. These do ressions serve to receive extending rounde projections 16 which are carried by a roller 17 The formation of the depressions 15 is such that there may be slig t longitudinal rolling movement of the roller 17. The roller itself has an outside surface which is concave, and which is adapted to receive and support a pipe such as indicated at 18, and from the construction it will be seen that the supporting contact for the pipe 18 is-what may be termed a rolling contact.

The pipe 18 will usually be covered by a suitable heat retaining cover which is indicated at 19, and this will be cut away as indicated at 19, so as to provide a direct support for the pipe 18 upon the roller 17.

The block 5 is adapted to receive and support the saddle portion of the pipe suporting construction, which has just been described, and with this in view the width of the slot which is. indicated at 5 is substantially the width of the web member 6 of the saddle. It will be noted that the outer surfaces of the member 5 are divergently slanting, and the de ree of slant whichthe side members of the lock 54may have is the same as the degree of slant which is given to the slanting surfaces 7" and 8, so that when the saddle member is assembled with respect to the block 5 the web member 6 will occup the groove 5, and the slanting surfaces and 8 will co-operate with the outside slanting surfaces of the block 5. This arrangement definitely positions the saddle portion of the pipe support so that it will not move from side to side, and the weight of the pipe together with the weight of the pi e supporting construction which has been 3- scribed holds the saddle in its proper position.

In Fig. 1 the drawing does-not show a tile section corresponding to the tiles marked 4 at that portion of the structure at which the pipe supporting construction is shown, but it will be understood that such a tile section is there used, and for the purpose of admitting the pipe supporting construction, the bottom 0 such a tile Wlll be provided with a suitable o ning, such as indicated at 4 in Fig. 2. T is opening will also serve as a convenient discharge for any seepage or moisture which may accumulate within the tile.

The manner of co-operation between the supporting block 5 and'the tile with whichit co-operates is clearly indicated in Fig. 8,

held in alignment, a pluralit and itwill be seen s the side ribs 5* and 5 on the block 5 wlllbe two points of support for the tile above the same so that the wei ht of the tile, and of course, the weight the fact that it is, practically speakin under manufacturing conditions impossi Is to produce a pe ectl round cradle of the same diameter as the iameter of the tile itself, and it therefore introduces uneven support. All this is obviated by the two-point support by the block 5 which has been described. I
